Diabetes is a complex metabolic disorder characterized primarily by impaired insulin secretion and insulin action. Insulin, produced by pancreatic β-cells, facilitates glucose uptake by tissues and regulates hepatic glycogen synthesis while inhibiting glycogen breakdown and gluconeogenesis. Insufficient insulin disrupts these processes, leading to increased hepatic glucose output and reduced peripheral glucose utilization, ultimately resulting in hyperglycemia.
Type 2 diabetes, accounting for approximately 90% of diabetes cases, is marked by hyperglycemia, insulin resistance, and a relative deficit in insulin secretion. The heterogeneity of the disease means that the degree of β-cell dysfunction and insulin resistance varies across individuals. Insulin resistance may contribute to additional metabolic disturbances, including dyslipidemia and elevated inflammatory activity, complicating therapeutic management. Conventional drug formulations face limitations such as suboptimal bioavailability, frequent dosing requirements, and lack of tissue-specific targeting, underscoring the need for advanced delivery strategies.
Nanoparticles offer multiple advantages as drug carriers in diabetes research:
Enhanced stability and bioavailability: Encapsulation within nanoparticles protects therapeutic molecules from degradation, increasing their stability in the gastrointestinal tract and extending systemic retention.
Efficient transport across biological barriers: Small particle size and high surface-to-volume ratio enable nanoparticles to traverse physiological barriers, allowing precise delivery to target tissues or cells.
Biocompatible polymer carriers: Natural polymers such as chitosan exhibit excellent biocompatibility and biodegradability. Beyond serving as carriers, these polymers may contribute to metabolic regulation, including modulation of lipid absorption, immune function, and nutrient utilization, supporting overall metabolic balance.
Nanoparticles enable advanced drug release and targeting strategies:
Stimuli-responsive systems: Nanocarriers can be engineered to release therapeutic agents in response to specific environmental cues, such as glucose concentration or oxidative stress levels, allowing dynamic, adaptive dosing.
Targeted delivery platforms: Surface modification of nanoparticles enhances their specificity for particular tissues or cells, minimizing systemic exposure while maximizing local therapeutic effect. Functionalized nanoparticles can also modulate inflammatory and oxidative processes associated with diabetic pathology.
Hybrid and multi-functional carriers: Biohybrid nanoparticles, which integrate natural membranes or vesicles with synthetic materials, combine high biocompatibility, prolonged circulation, and tissue-specific targeting. These platforms enable the concurrent delivery of multiple agents, addressing complex pathological features such as hyperglycemia and oxidative stress in a coordinated manner.
Nanoparticle-based strategies offer a versatile and precise approach for improving therapeutic efficacy in diabetes research. From simple polymeric carriers to complex stimuli-responsive and hybrid systems, nanotechnology provides a platform for innovative, efficient, and highly targeted interventions, with significant potential for advancing metabolic research and therapeutic development.

Nanoparticles can achieve precise targeting of pancreatic β-cells through surface functionalization. Specific ligands, such as antibody or peptide mimetics, are used to modify nanoparticle surfaces, enabling selective recognition of glucose-dependent insulinotropic peptide receptors on β-cells. Insulin-loaded nanoparticles enter β-cells via receptor-mediated endocytosis and release insulin in response to intracellular glucose levels.
Lipid-based nanoparticles functionalized with glucosamine molecules can mimic natural glucose metabolism pathways and target glucose transporters in insulin-sensitive tissues. These nanoparticles traverse cell membranes, facilitate glucose uptake in muscle and adipose tissue, and protect insulin from enzymatic degradation. Experimental evidence shows that nanoparticles modified with specific peptide sequences exhibit high β-cell affinity and enhance glucose-responsive insulin secretion in diabetic models.
Nanoparticles provide unique advantages in regulating diabetes-related oxidative stress. Selenium nanoparticles mimic glutathione peroxidase activity and efficiently scavenge excessive reactive oxygen species (ROS). Mesoporous silica nanoparticles loaded with quercetin reduce serum malondialdehyde levels while enhancing superoxide dismutase (SOD) activity in animal models.
Regarding inflammation, nanoparticles carrying resveratrol inhibit the NF-κB signaling pathway, reducing pro-inflammatory cytokines such as TNF-α and IL-6. Gold nanoparticles modulate Nrf2 signaling, strengthening cellular antioxidant defenses. Certain metal-organic framework nanoparticles simultaneously scavenge ROS and induce macrophage polarization from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype, mitigating chronic inflammation associated with diabetes.
Nanoparticles demonstrate considerable potential as gene delivery vectors. Cationic polymeric nanoparticles, such as polyethyleneimine derivatives, can electrostatically compact plasmid DNA encoding glucagon-like peptide-1 (GLP-1), forming stable nanocomplexes that achieve efficient hepatic cell transfection and sustained peptide expression.
Lipid nanoparticles have successfully delivered small interfering RNA (siRNA) targeting the glucagon receptor, achieving up to 70% gene knockdown in animal models with effects lasting over three weeks. Nanoparticles also protect protein therapeutics, such as insulin-like growth factor 1 (IGF-1), from enzymatic degradation, extending their half-life and enhancing biological activity.
Nanoparticles enhance drug bioavailability and stability through multiple mechanisms. Polymeric nanoparticles, such as PLGA-based core-shell structures, protect insulin from gastric acid and enzymatic degradation while facilitating intestinal uptake via endocytosis or paracellular transport, partially bypassing first-pass metabolism.
Self-assembled micelles formed from amphiphilic block copolymers create hydrophobic cores and hydrophilic shells, improving solubility and stability of poorly water-soluble drugs. Nanocrystal technology reduces drug particle size to the nanoscale, increasing surface area and dissolution rates.
Intelligent responsive systems further optimize drug delivery. pH-sensitive nanoparticles remain intact in gastric conditions and release payloads in neutral intestinal environments. Redox-sensitive carriers release drugs in high intracellular glutathione conditions, while glucose-responsive hydrogel nanoparticles adjust insulin release according to glucose levels. Collectively, these strategies enable controlled, stable, and efficient delivery of therapeutic agents, providing a versatile platform for diabetes-related research.

Nanoparticle platforms have emerged as highly promising carriers for antidiabetic drug delivery. Through precise engineering, these systems can overcome the limitations of conventional administration methods, enabling efficient, targeted, and controlled drug release.
Polymeric nanoparticles offer controlled physicochemical properties that facilitate sustained insulin release. Polyesters such as poly (lactic-co-glycolic acid) (PLGA) are widely used due to their biocompatibility and biodegradability, making them attractive carriers for oral insulin delivery. Studies indicate that modifying nanoparticle surface topography and linker length can significantly enhance interactions with intestinal receptors. For instance, PLGA nanoparticles functionalized with tetra-carbon linkers and garcinia-derived ligands achieved a 3.5-fold increase in oral bioavailability compared with non-functionalized carriers, demonstrating the potential of surface engineering for enhanced intestinal uptake.
Chitosan-based nanoparticles also exhibit advantages due to their mucoadhesive properties and ability to enhance mucosal permeability. Nanoparticles composed of chitosan and γ-polyglutamic acid achieved insulin loading of 16.3% and enabled sustained glucose-lowering effects in oral administration studies. These natural polymeric systems not only protect insulin from gastrointestinal degradation but also transiently modulate tight junctions to improve absorption.
Intelligent polymeric systems further enhance delivery precision. Amino acid-modified G-quadruplex hydrogels conjugated with formylphenylboronic acid can form modular, glucose-responsive insulin release platforms. In experimental models, these systems successfully maintained stable glucose levels, highlighting their potential for dynamic metabolic regulation.
Lipid-based nanocarriers, including liposomes and niosomes, provide biocompatible platforms for antidiabetic drug delivery. Liposomes derived from milk fat globule membranes (MFGM) demonstrate unique advantages for oral insulin transport, achieving enhanced systemic glucose control and supporting metabolic stability.
Niosomes loaded with goat casein-derived peptides (GCAPS) exhibit high encapsulation efficiency (94.98%) and small particle size (≈90 nm), significantly improving peptide stability and DPP-IV inhibitory activity under simulated gastrointestinal conditions. In insulin-resistant models, GCAPS-niosomes enhanced GLP-1 levels, modulated inflammatory markers, and positively influenced gut microbiota composition, collectively contributing to improved glucose homeostasis.
Solid lipid nanoparticles (SLNs) also show promise in oral insulin delivery. Palmitic acid-based SLNs achieved 43% encapsulation efficiency and maintained glucose-lowering activity for up to 24 hours, highlighting their capacity to protect bioactive molecules while enhancing absorption.
Inorganic and hybrid nanostructures provide innovative solutions for glucose regulation due to their catalytic activity and structural stability. Two-dimensional nanoenzyme platforms, such as 2D-like glucose oxidase@Cu-ZIF-8, exhibit enhanced glucose oxidation activity through copper-induced d-orbital modulation, increasing enzymatic activity three- to fourfold and reactive oxygen species generation six- to sevenfold.
Gold nanoparticles (20–70 nm) coated with insulin demonstrate prolonged glucose-lowering effects post-subcutaneous administration, and their high surface-to-volume ratio and functionalization potential make them versatile delivery systems. Bioinspired hybrid spheres (HSs), integrating inorganic nanoparticles with polymeric matrices, can perform combined adsorption, catalytic glucose oxidation, and pH-responsive drug release, significantly reducing hypoglycemic events in model studies.
Glucose-responsive nanomaterials adjust drug release in response to blood glucose levels. Phenylboronic acid (PBA)-functionalized nanoparticles undergo structural and phase transitions under hyperglycemic conditions, triggering insulin release. Enzyme-based systems employ glucose oxidase to convert glucose into gluconic acid, lowering local pH and activating pH-sensitive carriers. Chitosan microgels incorporating glucose oxidase and catalase can maintain glucose regulation for 24 hours, enhancing responsiveness while minimizing hydrogen peroxide accumulation.
Composite responsive nanoparticles integrate multiple stimuli, such as glucose and temperature sensitivity. For example, p(AAm-PBA-b-DGMPA) nanoparticles provide sustained glucose control for up to 48 hours following subcutaneous administration, improving precision and safety while reducing hypoglycemia risk.
